All objects such as ( Information, Decision, Invetigations) are interlinked

Its shows the full description and flow of Information, Reseach, Invetigations, Projects, Decision

Login Activity Diagram of Decision Support System:

This is the Login Activity Diagram of Decision Support System, which shows the flows of Login Activity, where admin will be able to login using their username and password. After login user can manage all the operations on Projects, Information, Decision, Invetigations, Reseach. All the pages such as Decision, Invetigations, Reseach are secure and user can access these page after login. The diagram below helps demonstrate how the login page works in a Decision Support System. The various objects in the Invetigations, Projects, Information, Decision, and Reseach page—interact over the course of the Activity, and user will not be able to access this page without verifying their identity.

Decision Support System Class Diagram describes the structure of a Decision Support System classes, their attributes, operations (or methods), and the relationships among objects. The main classes of the Decision Support System are Decision, Information, Reseach, Projects, Invetigations, Researcher.

Classes of Decision Support System Class Diagram:

Decision Class : Manage all the operations of Decision

Information Class : Manage all the operations of Information

Reseach Class : Manage all the operations of Reseach

Projects Class : Manage all the operations of Projects

Invetigations Class : Manage all the operations of Invetigations

Researcher Class : Manage all the operations of Researcher

Classes and their attributes of Decision Support System Class Diagram:

Class Diagram of Decision Support System :

This is a Component diagram of Decision Support System which shows components, provided and required interfaces, ports, and relationships between the Decision, Invetigations, Reseach, Information and Researcher. This type of diagrams is used in Component-Based Development (CBD) to describe systems with Service-Oriented Architecture (SOA). Decision Support System UML component diagram, describes the organization and wiring of the physical components in a system.

Decision Support System Data flow diagram is often used as a preliminary step to create an overview of the Decision without going into great detail, which can later be elaborated.it normally consists of overall application dataflow and processes of the Decision process. It contains all of the userflow and their entities such all the flow of Decision, Information, Research, Projects, Investigations, Researcher, Login. All of the below diagrams has been used for the visualization of data processing and structured design of the Decision process and working flow.

This is the Zero Level DFD of Decision Support System, where we have eloborated the high level process of Decision. It’s a basic overview of the whole Decision Support System or process being analyzed or modeled. It’s designed to be an at-a-glance view of Investigations,Researcher and Login showing the system as a single high-level process, with its relationship to external entities of Decision,Information and Research. It should be easily understood by a wide audience, including Decision,Research and Investigations
In zero leve DFD of Decision Support System, we have described the high level flow of the Decision system.

High Level Entities and proccess flow of Decision Support System:

Managing all the Decision

Managing all the Information

Managing all the Research

Managing all the Projects

Managing all the Investigations

Managing all the Researcher

Managing all the Login

First Level Data flow Diagram(1st Level DFD) of Decision Support System :

First Level DFD (1st Level) of Decision Support System shows how the system is divided into sub-systems (processes), each of which deals with one or more of the data flows to or from an external agent, and which together provide all of the functionality of the Decision Support System system as a whole. It also identifies internal data stores of Login, Researcher, Investigations, Projects, Research that must be present in order for the Decision system to do its job, and shows the flow of data between the various parts of Decision, Research, Researcher, Login, Investigations of the system. DFD Level 1 provides a more detailed breakout of pieces of the 1st level DFD. You will highlight the main functionalities of Decision.

Main entities and output of First Level DFD (1st Level DFD):

Processing Decision records and generate report of all Decision

Processing Information records and generate report of all Information

Processing Research records and generate report of all Research

Processing Projects records and generate report of all Projects

Processing Investigations records and generate report of all Investigations

Processing Researcher records and generate report of all Researcher

Processing Login records and generate report of all Login

Second Level Data flow Diagram(2nd Level DFD) of Decision Support System :

DFD Level 2 then goes one step deeper into parts of Level 1 of Decision. It may require more functionalities of Decision to reach the necessary level of detail about the Decision functioning. First Level DFD (1st Level) of Decision Support System shows how the system is divided into sub-systems (processes). The 2nd Level DFD contains more details of Login, Researcher, Investigations, Projects, Research, Information, Decision.

Low level functionalities of Decision Support System

Admin logins to the system and manage all the functionalities of Decision Support System

This ER (Entity Relationship) Diagram represents the model of Decision Support System Entity. The entity-relationship diagram of Decision Support System shows all the visual instrument of database tables and the relations between Information, Projects, Decision, Researcher etc. It used structure data and to define the relationships between structured data groups of Decision Support System functionalities. The main entities of the Decision Support System are Decision, Information, Reseach, Projects, Invetigations and Researcher.

This is the UML sequence diagram of Decision Support System which shows the interaction between the objects of Decision, Reseach, Information, Projects, Researcher. The instance of class objects involved in this UML Sequence Diagram of Decision Support System are as follows:

Decision Object

Reseach Object

Information Object

Projects Object

Researcher Object

Login Sequence Diagram of Decision Support System:

This is the Login Sequence Diagram of Decision Support System, where admin will be able to login in their account using their credentials. After login user can manage all the operations on Information, Decision, Reseach, Researcher, Projects. All the pages such as Reseach, Researcher, Projects are secure and user can access these page after login. The diagram below helps demonstrate how the login page works in a Decision Support System. The various objects in the Researcher, Information, Decision, Reseach, and Projects page—interact over the course of the sequence, and user will not be able to access this page without verifying their identity.

This is the UML sequence diagram of Decision Support System which shows the interaction between the objects of Decision, Reseach, Information, Projects, Researcher. The instance of class objects involved in this UML Sequence Diagram of Decision Support System are as follows:

This Use Case Diagram is a graphic depiction of the interactions among the elements of Decision Support System. It represents the methodology used in system analysis to identify, clarify, and organize system requirements of Decision Support System. The main actors of Decision Support System in this Use Case Diagram are: Super Admin, System User, User, Anonymous Users, who perform the different type of use cases such as Manage Decision, Manage Information, Manage Reseach, Manage Projects, Manage Invetigations, Manage Researcher, Manage Users and Full Decision Support System Operations. Major elements of the UML use case diagram of Decision Support System are shown on the picture below.
